ChainSnip

Product Introduction

1. Definition: ChainSnip is a specialized Software-as-a-Service (SaaS) platform for automated blockchain data preservation. It functions as a web archiving and timestamping service specifically engineered for cryptocurrency wallet balances and transaction histories displayed on blockchain explorers.
2. Core Value Proposition: It exists to solve the critical problem of provable, historical crypto asset verification for financial compliance. ChainSnip provides accountants, auditors, and financial professionals with timestamped, tamper-evident cryptographic proof of wallet balances at specific period-ends, transforming manual, error-prone verification into an automated, audit-ready process.

Main Features

1. Automated Month-End Snapshot Capture: ChainSnip automatically navigates to specified blockchain explorer URLs (e.g., Etherscan, BscScan, Solscan) at 23:59 UTC on the last day of each month. It captures a full-page screenshot of the wallet's balance and transaction overview, creating a static, visual record of the live explorer page without manual intervention.
2. Cryptographic Timestamping & Hashing: At the moment of capture, each snapshot file is processed through a SHA-256 hashing algorithm. The resulting hash, along with a precise UTC timestamp, is immutably recorded. This creates a tamper-evident seal; any subsequent alteration of the image file would produce a different hash, providing verifiable proof the record is original.
3. Historical Balance Reconstruction via Archive Nodes: For missed periods or historical verification, ChainSnip queries blockchain archive nodes to reconstruct wallet balances at any past date or block height. This is critical for accurately reporting balances of rebasing tokens (like stETH) and for audits of prior periods, providing data directly from the chain state at that historical point.
4. Client-Centric Organization & Export: Users can group wallets by client or entity. The platform maintains a dated ledger of all captures, allowing for organized retrieval. Complete sets of evidence can be exported in a structured format (e.g., packaged snapshots with a manifest) for direct delivery during financial audits or tax filing processes.
5. Multi-Chain and Multi-Explorer Support: The service supports over 50 blockchain explorers across major networks including Ethereum (EVM), Solana, Bitcoin, and Cosmos. This ensures consistent proof-generation methodology across a diverse portfolio of digital assets held on different blockchains.

Problems Solved

1. Pain Point: The manual process of taking and storing screenshots of blockchain explorer pages for month-end balance verification is unreliable, time-consuming, and lacks defensible audit trails. Auditors frequently question the authenticity and timing of such evidence.
2. Target Audience: Primary users are Crypto-Tax Accountants, Financial Auditors at accounting firms, Solo CPA practitioners with crypto clients, and CFOs/Financial Controllers at blockchain-native companies (DAOs, crypto funds) who require rigorous financial reporting.
3. Use Cases: Essential for generating verifiable proof of holdings for annual financial statement audits, quarterly reviews, tax return preparation and defense, fund NAV calculations, and providing immutable evidence during regulatory examinations or due diligence for fundraising.

Unique Advantages

1. Differentiation: Unlike generic screenshot tools or manual methods, ChainSnip is built specifically for financial evidence standards. It surpasses simple API balance pulls by providing a visual, context-rich snapshot of the official explorer page—the same source an auditor would check—enhanced with cryptographic verification that API data alone cannot provide.
2. Key Innovation: The combination of scheduled web archiving targeted at blockchain explorers with integrated cryptographic hashing at the point of capture. This creates a "proof-of-existence" and "proof-of-integrity" chain of custody for financial data, bridging the gap between dynamic blockchain data and static audit evidence requirements.

Frequently Asked Questions (FAQ)

1. How does ChainSnip provide proof that a snapshot wasn't altered later? Each snapshot is cryptographically hashed using the SHA-256 algorithm at the exact moment of capture. The hash is stored separately. To verify integrity, you can re-hash the downloaded snapshot file; if it matches the original stored hash, it proves the file is unaltered since capture.
2. Can ChainSnip capture balances for tokens that change automatically, like stETH? Yes. For historical lookups, ChainSnip queries blockchain archive nodes to read the exact wallet state at a specific past block, correctly reflecting the balance of rebasing or yield-bearing tokens at that precise historical moment, which ordinary explorers may not display accurately for past dates.
3. What happens if a blockchain explorer's website design changes? ChainSnip's capture engine is designed to target the core balance and transaction data on explorer pages. While minor UI changes may occur, the service focuses on the essential data points required for audit proof. The platform monitors and adapts to major changes to ensure reliability.
4. Is the evidence from ChainSnip legally admissible in an audit? While ChainSnip provides robust, tamper-evident evidence designed to meet auditor scrutiny, the final determination rests with the auditing firm and applicable jurisdiction. The timestamped and hashed proof is structured to satisfy standard audit evidence criteria for completeness, accuracy, and verifiability.
5. How does ChainSnip handle private or wallet-labeled addresses? ChainSnip only captures publicly available information from blockchain explorers. It cannot access private data. If a wallet's label or name is public on the explorer (e.g., "Binance 8" wallet), it will appear in the snapshot; otherwise, only the public address is shown.
